Witness the Seven Sisters Eclipse in July 2025

2025-07-24

On July 20, 2025, a celestial event awaits stargazers across much of the U.S. and Canada: the moon will occult the Pleiades star cluster, also known as the Seven Sisters. This monthly occurrence, happening since September 2023, offers a chance to witness the moon temporarily blocking these young stars. Visible to the naked eye in the early morning hours, the best viewing will be from dark locations away from city lights. Other celestial events in July 2025 include Venus, Jupiter, and Mars conjunctions with the moon.

Landmark Alzheimer's Study Possibly Faked: 16 Years of Research Misdirected?

2025-06-13

A landmark 2006 Nature study on Alzheimer's disease, which proposed the amyloid hypothesis (that amyloid-beta protein is the cause), may have been based on fabricated images. This has cast doubt on 16 years of research and funding allocation. A whistleblower revealed potential image manipulation, prompting an investigation. Millions of dollars in research funding may have been wasted, and more importantly, millions of Alzheimer's patients may have missed out on effective treatments. The investigation is ongoing, and the research community is reevaluating its approach to Alzheimer's research, advocating for broader funding distribution to prevent similar incidents.

Earth's Water: Homegrown, Not Alien?

2025-04-20

A new study published in Icarus challenges the long-held belief that Earth's water originated from space. Researchers analyzed an enstatite chondrite meteorite, whose composition resembles early Earth. Using a synchrotron, they discovered hydrogen within the meteorite, proving it wasn't terrestrial contamination. This suggests the building blocks of Earth were far richer in hydrogen than previously thought, providing enough to account for Earth's water. The study strongly supports the theory that Earth's water is native, a natural consequence of the planet's formation, rather than a result of asteroid impacts.

The Renegade Doctor Who Drank Bacteria and Won a Nobel Prize

2025-02-02

For years, Australian physician Barry Marshall witnessed ulcer patients suffering immensely, even dying. He hypothesized, and ultimately proved, that the persistent bacteria Helicobacter pylori, not stress, was the culprit. To demonstrate this groundbreaking conclusion, he ingested a bacterial culture, experiencing gastritis firsthand. His work earned him a Nobel Prize, revolutionizing ulcer treatment and pioneering the use of weakened Helicobacter for flu vaccines. His story underscores the importance of challenging authority, pursuing truth, and maintaining an open mind about the unknown.

Iodized Salt and the Unexpected IQ Boost

2025-01-29

New research reveals that adding iodine to salt in the US since 1924 significantly boosted cognitive abilities across the American population throughout the 20th century. Initially implemented to reduce goiter, studies now show iodine's crucial role in brain development. By comparing military enlistment data from before and after 1924, researchers found a 15-point IQ increase in low-iodine areas. While early iodine supplementation caused some thyroid-related deaths, the initiative virtually eradicated iodine deficiency and its consequences. This discovery may also partially explain the Flynn Effect – the observed rise in IQ scores throughout the 20th century – suggesting iodine contributed to a significant portion of this increase.
